Answer:
The answer is A. 198 and B. 370.
Step-by-step explanation:
A number is divisible by 2 if the digit at unit place is either 0 or multiple of 2. So a number is divisible by 2 if digit at its units place is 0, 2, 4, 6 or 8. Numbers divisible by 2 are called even numbers. Numbers not divisible by 2 are called odd numbers.
198 divided by 2 equals 99, which is a whole number with no remainder.
370 divided by 2 equals 185, which is a whole number with no remainder.
535 divided by 2 equals 267.5, which is not a whole number and has a remainder of .5.
1\tfrac{2}{5} \div \frac{8}{9}
1 5/2 ÷ 9/8
Answer:
Step-by-step explanation:
What you wrote below the top line and the bottom line are not the same thing.
I think you really want the second line, but one can't be sure.
(1*2 + 5)/2 div (9/8)
7/2 // 9/8
7/2 * 8*9
7*8/18 = 56/18 = 28/9
If you really do want the top line (the latex) it is different.
1 2/5 div (8/9) Is there such a thing as tfrac? I didn't know this but there is.
(1*5 + 2)5 // (8/9)
7/5 // 8/9 Invert the bottom fraction and multiply
7/5 * 9 / 8
63 / 40
1 23/40

URGENT PLEASE HELP: x = -pi/2 is an asymptote in the graph of y = tanx.
True or False
Answer:
Step-by-step explanation:
tan is the same thing as sin/cos. therefore,
[tex]tan(-\frac{\pi}{2})=\frac{sin(-\frac{\pi}{2}) }{cos(-\frac{\pi}{2}) }[/tex]
[tex]sin(-\frac{\pi}{2})=-1[/tex] and [tex]cos(-\frac{\pi}{2})=0[/tex] so
[tex]tan(-\frac{\pi}{2})=-\frac{1}{0}[/tex] which is undefined. On the graph, this is represented by an asymptote. So your answer is true.

Evaluate the function
f(x)=−4x^2+6x−4
Find f(5)
Hey there!
1. How to find f(5)?
To find f(5) - simply substitute x = 5 in the function. f(5) means the value of f(x) at x = 5.2. Substitution and Evaluate
[tex] \large{f(5) = - 4( {5})^{2} + 6(5) - 4}[/tex]
Remember to follow the PEMDAS/BODMAS rules! Exponent comes before multiplication.
[tex] \large{f(5) = - 4(25) + 30 - 4} \\ \large{f(5) = - 100 + 30 - 4} \\ \large{f(5) = - 74}[/tex]
3. Final Answer
f(5) = -74If you have any questions regarding the question or my answer, feel free to ask!

Answer:
AD = 6
Step-by-step explanation:
If a radius is perpendicular to a chord, then it bisects the chord.
Here XB is the radius, AC is the chord. Given XB and AC are perpendicular to each other. Therefore, XB bisects AC at D.
So,
[tex]AD = \frac{1}{2} \times AC = \frac{1}{2} \times 12 = 6[/tex]

9514 1404 393
Answer:
2 – will3 – will4 – will notStep-by-step explanation:
Whether the offered numbers will satisfy the inequality is more easily seen by solving it for x.
6 + 3x ≤ 15
3x ≤ 9 . . . . . . . . . subtract 6 from both sides
x ≤ 3 . . . . . . . . . . divide by 3
This is "x is less than or equal to three."

a carton contains 1 3/4 quarts of ice cream. One serving is a 1/5 of a quart. How many servings are in the carton?
Answer: 8 3/4
Explanation: Well in order to solve this equation, you must make the denominators equivalent. A common factor between 4 and 5 is 20. But since we multiplied the denominators, we have to do the same to the numerators. 3 x 5 = 15. 1 x 4 = 4. Our new fractions are now 1 15/20 and 4/20. Now that we have made our denominators equivalent, we can divide. 1 15/20 divided by 4/20 is 8 15/20. But we are not done yet, after we must simplify the fraction. Which would be 8 3/4.

Consider the equation below
-2(bx -5 ) =16
Answer:
bx = - 3
Step-by-step explanation:
- 2(bx - 5) = 16
- 2bx + 10 = 16
- 2bx + 10 - 10 = 16 - 10
- 2bx = 6
- 2bx ÷ - 2 = 6 ÷ - 2
bx = - 3
Question 3 math help please show work
Answer:
Use the referent of an adult stride (about 1 yard) to measure the dimensions of the area that will be covered by sod. Use the dimensions to calculate the area in square yards.
Step-by-step explanation:
This seems to be a relatively vague question, but it was requested so I'll try my best.
There's practically no way to accurately measure the area to be covered by sod without using a reference. I couldn't help but notice the list of references above the question, and I presume they are correlated. Since the length of an adult stride is 1 yard, you can use an adult stride as a reference to relatively accurately measure the dimensions of the area that needs to be covered. The method to find the area varies with the shape of the area, but assuming you can accurately find the area, this is a plausible way to estimate the area needed to be covered by sod. As an alternative, since the question stipulates sod can only be purchased in square yards or square meters, you can use a doorway (about 2 meters) in the list of references above the question to also measure the dimensions of the area. This is less practical because an adult stride is more mobile than a door.

-18 - 4y > 20
Can some1 solve this pls?
Answer:
y < -19/2
Step-by-step explanation:
-18 - 4y > 20
Add 18 to each side
-18+18 - 4y > 20+18
-4y > 38
Divide each side by -4, remembering to flip the inequality
-4y/-4 < 38/-4
y < -19/2
Answer:
y < -9.5
Step-by-step explanation:
-18 - 4y > 20
Add 18 to both sides of the inequality.
-18 + 18 - 4y > 20 + 18
Add -18 + 18 which gets you 0.
0 - 4y > 20 + 18
Subtract 0 - 4y which gets you -4y.
-4y > 20 + 18
Add 20 + 18 to get 38.
-4y > 38
Divide both sides by -4 and change the inequality direction.
y < 38/-4
Cancel out 2 as a common factor from 38/-4.
y < 19/-2
Divide 19 / -2 which gets you -9.5.
-9.5

(24 + 4) ÷ 2 = (24 ÷ 2) + ( __ ÷ 2)
i dont know this
Answer:
4
Step-by-step explanation:
(24+4) ÷ 2 = (24 ÷ 2) + (4 ÷ 2)
28÷2 = 14
Check:
24÷2 = 12
4÷2 = 2
12+2=14
Answer:
The answer is 4.
Step-by-step explanation:
(24 + 4) ÷ 2 = (24 ÷ 2) + (x ÷2)
=28 ÷ 2 = 12 + (x÷2)
14 = 12 + (x ÷ 2)
14 - 12 = x ÷ 2
2 = x ÷ 2
2 × 2 = x
x = 4
Select the correct answer. The sum of two numbers is -18. If the first number is 10, which equation represents this situation, and what is the second number? A. The equation that represents this situation is 10 − x = -18. The second number is 28. B. The equation that represents this situation is 10 + x = -18. The second number is -28. C. The equation that represents this situation is x − 10 = -18. The second number is -8. D. The equation that represents this situation is -10 + x = -18. The second number is -8.
Answer:-28
Step-by-step explanation:
Let A is the second number
the first number is 10.
The total is -18
=> 10 + A =-18 <=> A=-18-10=-28
